Your Data Never Leaves Your Device

Every tool runs entirely in your browser. Nothing you type is uploaded, stored, or logged on our servers.

100% Client-Side

The Merge PDF tool combines any number of PDF files into a single document. Drag files into the order you want them stitched together, then merge — the whole process runs inside your browser using pdf-lib, so your documents are never uploaded anywhere.

Useful for combining scanned pages, stitching together invoices or reports, or assembling a single PDF from several exports before sending it on.
